The Nimzo-Indian Defence: 1.d4 Nf6 2.c4... 4.e3 arises after 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 and falls under ECO code E40. White judges that an immediate 4...Bxc3 poses no real threat and that provoking the exchange with 4.a3 is premature. Instead, 4.e3 opens the diagonal for the light-squared bishop, which typically develops to d3 where it strengthens White's grip on the crucial e4 square. Black has three principal responses, and in each case White faces a choice between developing the knight to e2 (5.Nge2) or placing the bishop on d3 first (5.Bd3). With 2 million Lichess games across all rating levels, it is a well-established opening choice.
